| eval build = coalesce('abc.build', 'def.build', 'ghi.build') ``` the above is equivalent to the following
Splunk eval if statement manual#
This is less obvious what it does, so I also put a manual enumeration equivalent in comments. In the following, I will use foreach command to iterate. (Identical top node will make the search infinitely simpler.) The function to call is coalesce but you will need some way to enumerate the top nodes. Do the top node really change from event to event in real data?Īssuming that the top node does change from event to event, you'll have to find some way to get rid of because they do not factor into your desired result.
You want to chart by sw, not hardware.If there is no correlation, the best you can do is your search 1 with append. What is the result that you expect from the illustrated data? What is the logic to "cross" events? Is there any key to correlate the two builds? (I don't see any in your illustrated data.) What is the purpose of that last search for abc attributes after you stats over def builds? The best way to start is to describe your use case. Of course, even if you do not have that eval, the first stats will not give you value for avg_a_duration, either, because the abc.duration only exists with abc.build and abc.hardware. This wipes avg_a_duration out with null value because abc.duration no longer exists. | eval avg_a_duration=abc.duration ```<= this is a limit line I want to implement based on the next search ``` | stats avg(d_duration) as avg_d_duration, avg(a_duration) as avg_a_duration by def.build, def.hardwareĪfter this, abc.duration no longer exist in data stream, only avg_a_duration. Please let me know if I need to clarify any parts of the question. Sorry, I'm fairly new to Splunk, so there's a lot of learning on my end. <= This is what I'm looking for, but I'm trying to achieve this with the results from the first search.
In Example 3, I see avg_a_duration is constant for both appended search results. In Example 2, I see the same results as in example1, but just a different column - 'g_duration' In Example1, I see the results from the first search appended to the second search
|eval avg_d_duration = round(avg(avg_d_duration),3) | stats avg(d_duration) as avg_d_duration, avg(avg_a_duration) by def.build, def.hardware | stats avg(d_duration) as avg_d_duration, avg(g_duration) by def.build, def.hardware |eval avg_a_duration = round(avg(avg_a_duration),2) | stats avg(d_duration) as avg_d_duration, avg(avg_a_duration) by def.build, def.hardwareeval avg_d_duration = round(avg(avg_d_duration),3) | stats avg(avg(a_duration) as avg_a_duration by def.build, def.hardware This is still the case even if I specify the same variable in both stats. Then we used our required regular expression to match.I want a single value from one of the event, but I want to extend this for all the results captured from the later stats, how would I do that?Īt the moment, when I use append, that only appends the first result with the latter result. we want to match our given regular expression with the “ SegmentNo” field. Now coming back to the “ match” function, here we have mentioned a field called “ SegmentNo”. That’s why we have used the “ if” function, which means whenever the match condition will satisfy it will return “ Yes” otherwise “ NO”. Because the “ match” function can match the events but can’t populate any new field values. Then we have a “ match” function with “ if” to produce results in “ match” filed. In the beginning, we used the “ table” command to give a tabular showcase for all required fields. Here we have some financial data in our “ finance” index. | table SegmentNo,Segment,Country,Product,UnitsSold,SalePrice,Sales,Profit X: Name of the field where you want to match the given regex with.Įxample: index="finance" source="Financial*" NOTE: “^” and “$” characters are used in regular expressions to identify the start and end of the string.
Splunk eval if statement full#
Try to mention “^” and “$” signs with the regular expression to perform a compact and full match in case of “match” function.Functions of “match” are very similar to case or if functions but, “match” function deals with regular expressions.This function takes matching “REGEX” and returns true or false or any given string.we can consider one matching “REGEX” to return true or false or any string.
